How to calculate rough weight of
iron and steel castings
- on Nov. 25, 2011
Iron foundries need to calculate the
estimated rough casting weights
during quotation process. Estimated
rough weight is very important for
the prices. Lower and higher weight
will directly affect the prices of
iron and steel castings.

Rough Machining for Metal
Castings - on Nov.
24, 2011
Rough machining is important for
exported metal castings. It can
largely reduce the defective rates
of castings, and can meet the
dimensional requirements to some
positions.

Advantages and Disadvantages of
Resin Sand Casting Process
- on Nov. 22, 2011
Resin sand is a common casting
material in foundry industry, so
resin sand casting process is a main
casting method for iron castings.
This article will introduce its
advantages and disadvantages to
buyers for iron castings.
-
casting flask, moulding flask,
sand box, molding box
- on Nov. 21, 2011
Casting flask is also known as
moulding flask, sand box or molding
box. It is an essential tooling in
the production of sand castings.
Suitable casting flasks could
improve the casting quality, and
reduce the consumption of molding
sand, so to reduce the production
costs.

The Advantages of Metal Casting
- on Nov. 17, 2011
The metal casting process is almost
free from the restrictions of the
size, thickness and shape of
castings, casting wall thickness can
be up to 0.3-1000mm, the length
varies from a few millimeters to ten
meters, and the quality can be from
a few grams to more than 300t.

Development of Metal Foundries in
China - on Nov. 16,
2011
China is changing from a large iron
casting producer to a cast iron
power. We must overcome energy,
resources, human resources
bottleneck and environmental issues
in reality.

KS D4101 - Standard for
Engineering Structural Cast Steel
- on Nov. 11, 2011
This is a Korea standard for the
chemical analysis and mechanical
properties of engineering structural
steel. This material has higher
strength, mechanical properties,
shock resistance and corrosion
resistance.

Brief of China Metal Foundry
Industry - on Nov.
10, 2011
For many metal casting buyers,
especially those foreign buyers,
some basic facts of China’s metal
foundry industry are significant, so
in this article, we will provide you
some basic information for your
reference.
-
Why is rough casting weight
important? - on Nov.
07, 2011
Rough casting or raw casting means
the metal castings without
machining, or before machining
process. Rough casting weight
is larger than machined
casting weight, but why is this
weight so important for the
casting prices?
-
Standard Specifications for Metal
Casting Tolerances - ISO 8062, ISO
286, ANSI B4.1, ISO 2768
- on Nov. 04, 2011
These standards provide guidance for
metal casting linear dimension
tolerances where no other
requirements exist for form, fit or
function (general tolerances). We
made a comparison table for ISO
8062, SFSA 2003, ISO 286-2, ISO 2768
and ANSI B4.1.

Gray Iron Castings Hardness
Requirements - on
Nov. 03, 2011
They are used as the general
engineering gray iron castings which
take tensile strength as the main
consideration, and are classified
into different grades according to
the tensile strength of different
test bars.
-
The advantages of ductile iron
manhole cover - on
Nov. 02, 2011
Ductile iron manhole covers are made
primarily by ductile iron, or called
as nodular iron or sg iron. Whether
the quality is good or bad depends
on the nodularity. Rust-proof
asphalt pain is commonly used in
casting process.
